I’m no constitutional law expert, but does “full faith and credit” have anything to do with the kind of paperwork one state can require from another if it exists? Does it mean Hawaii can dictate in such cases? That’s hard to fathom. I always thought “full faith and credit” meant that one state would have to honor the mere validity of another state’s laws. (Not necessarily acquiesce in all of their administrative decisions.)
It would also make a difference if the Hawaii regulations still allowed for the provision of a certified copy of the original birth certificate if one should be specifically requested. I would be surprised if there were no such option available.
U.S. Constitution:
Full faith and credit shall be given in each state to the public acts, records, and judicial proceedings of every other state. And the Congress may by general laws prescribe the manner in which such acts, records, and proceedings shall be proved, and the effect thereof.
